 * represents the schemas against which validation should occur, i.e. the 
 * current schema. The types of schemas referenced in this list must match 
 * the type specified with <code>schema-type</code>, otherwise the behavior 
 * of an implementation is undefined.  The schemas specified using this 
 * property take precedence to the schema information specified in the 
 * document itself. For namespace aware schema, if a schema specified using 
 * this property and a schema specified in the document instance (i.e. using 
 * the <code>schemaLocation</code> attribute) in a schema document (i.e. 
 * using schema <code>import</code> mechanisms) share the same 
 * <code>targetNamespace</code>, the schema specified by the user using this 
 * property will be used. If two schemas specified using this property share 
 * the same <code>targetNamespace</code> or have no namespace, the behavior 
 * is implementation dependent.  If no location has been provided, this 
 * parameter is <code>null</code>. 
 * <p ><b>Note:</b>  The <code>"schema-location"</code> parameter is ignored 
 * unless the "schema-type" parameter value is set. It is strongly 
 * recommended that <code>Document.documentURI</code> will be set so that an 
 * implementation can successfully resolve any external entities referenced. </dd>

 * the implementation, based on the schema languages supported and on the 
 * schema language used at load time. If no value is provided, this 
 * parameter is <code>null</code>. 
 * <p ><b>Note:</b>  For XML Schema [<a href='http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/'>XML Schema Part 1</a>]
